GRAMOPHONE ATTACHMENT FOR MUSIC-BOXES.

SPECIFICATION forming part of Letters Patent No. 755,946, dated March 29, 1904.

Application filedMarch 17, 1902,

- J r., a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements infGramophone Attachments for Music-Boxes, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention has reference to the provision of a novel combination of sound record supporting devices, with a reproducer therefor, means for supporting the said mechanism and devices in proximity to a music box or other equivalent apparatus having a suitable driving spring mechanism, and driving means for imparting movement to the sound record supporting mechanism from the driving mechanism of the music box.

Another object of my present invention is the provision of an apparatus of the type described, which can be manufactured and put on the market at a low price, because it is not necessary in conjunction with the same to supply any driving mechanism, the whole device being adapted for attachment to some ordinary form-of music box or other like apparatus, which is already provided with driving mechanism, and thereby make it possible to use the driving mechanism of the music box for actuating or furnishing requisite power to the gramophone attachment.

The above, as well as such other objects as may hereinafter appear, I attain by means of a construction which I have illustrated in preferred form in the accompanying drawings, in which Figure 1 is a side elevation of an apparatus embodying my improvements,

Figure 2 is a plan View thereof, I 1 Figure 3 is a view in section, showing certain of the interior parts of the device in ele Vation,

Figure 4: is a transverse section on the line 1 of Figure 3,

Figure 5 is a detail, showing the method of mounting the lever that carries the reproducing or sound box,

Figure 6 is a section on the line 6 of Figure 3, and

Serial No. 98,617. (No model.)

Figure 7 is a partial plan view of the driving disk of the music box.

Referring now more particularly to Figures 1 and 2 it will be seen that upon a music box 8, by means of a bracket 9, which has an extensible arm 10 having tubular engagement with the arm 9, I support a lever 11, which, by means of the device 12, carries a horn 13, the smaller end of which is mounted on a sound or reproducing box 14, which is also supported by the lever 11. By referring now to Figures3 to 7 inclusive, it will be seen how I have arranged the details of the mechanism already referred to. The bracket 9 is secured to the side of the box 8 by means of the clamp device having the thumb-screw 16: and upon the shaft 17, which is the shaft of the music box that carries the rotating disks which occupy the position indicated at 18, there is mounted a bracket 19 which extends around the disk 18 and upwardly, and supports the record carrying device 20, the record in this case being of the flat disk type, as indicated at 21.

The bracket 19 carries a spindle 22, on the upper end of which is a gear 23, of relatively large diameter, and on the lower end of which is a small gear or pinion 24, the latter being constructed to mate with a gearing 25, which is constructed to be rotated by the disk 18 on the shaft 17 of the music box, the device as shown having the ring firmly secured to the disk 18, which may take the place of the record disk of the music box, and is substantially like the same, save that the projections, or devices which produce the sound in the music box maybe omitted the disk 18 being a plain disk, save for the apertures arranged around its edge, which I have marked 25 (see Figure 7), which apertures engage the teeth 26 of the wheel 27, which latter in turn is driven from the gear 28 through the gear 29, and spring mechanism 30. The spring mechanism 30 has the usual, or any preferred form of governing mechanism,- as for example the fan 31 driven by the gear 32, which mechanism serves to control the speed of the device. At 33 is indicated a squared end on the shaft 3 1, which carries the spring mechanism, the squared end serving for the purpose of application of a key or other winding device, the shaft 341 being also provided with the usual form of ratchet wheel 35, to hold the spring when wound.

In order to put the bracket 19 in place on the shaft 17, the spindle 36 which is mounted pivotally at 87, as is usual in devices of this character, upon a bracket 38, is disengaged from the shaft 17 and raised up out of the way, so that the parts 19 and 18, with the gearing 25 attached to 18, can be put in place as shown.

Referring now to Figure 6 it will be seen that the record supporting plate 20 is carried on a conical part 20 so that it can be lifted ofi' readily when desired, the conical part 20 being formed on the shaft 39, which is supported by a ball-bearing 40, and on its lower end has a pinion 41, which is driven from the gear 23.

As shown in Figure 1, the arm 10 is square and tubular, and has within it a square tubular extension of the bracket 9, the two parts being capable of telescopic movement relative to each other, and provided with locking means in the shape of a' screw 10, this provision being for the purpose of getting proper adj ustment of the sound box and the lever 11 which carries it relative to the record 21.

The lever 11 is carried upon a notch 11 formed in the lower face thereof, there being a plurality of such notches to permit the position of the lever to be shifted, so that either one or the other of said notches, as preferred, may be caused to engage the supporting pin 11",v carried upon the pivotal supporting device 11, mounted in the end of the arm 10.

Briefly described, the operation of my invention is as follows:

The spindle 36 having been raised out of the way, the bracket 19 with the disk 18 and attached gear ring 25 are put in place as shown in Figure 3, and the bracket 9 is secured as also shown in Figure 3 to the side 15 of the music box, and the sound box 14: having been properly adjusted, the device is started, when the spring mechanism 30 will drive through the train of gears shown, the disk 18 and this in turn the gear ring 25, and this through the train of gears shown, the record plate 20, carrying the record around, as is usual in mechanism of this class. By merely removing the brackets 9 and 19 with their connected parts, the gramophone attachment is taken ofi the music box, which can then be used as before, simply as a music box, by the substitution of a music record in place of the disk 18, which comes off when the bracket 19 is removed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a music box, a driving mechanism therefor, a disk driven by said driving mechanism, a shaft upon which said disk is mounted, a bracket carrying a gramophone record, means for driving said gramophone record from said disk, and sound reproducing mechanism mounted adjacent to said record, substantially as described.

2.
